I know a bunch of you will automatically come to the conclusion that N,N-Dimethyltryptamine is just a hallucinogenic molecule that alters the way we perceive things and that seems like a pretty solid judgement to make.

But first you must question how it is doing that and why is it doing it in such a common fashion?

People who consume large doses of DMT experience an odd sensation, a static noise getting louder and louder and then "death". They are pulled through a tunnel into another "dimension", some would say. They see geometric shapes that are not possible. A 4D shape that is not describable in 3D. They also describe that when they land in this other place, they are instantly greeted with "entities" that always wish to calm them down, make them feel safe, show them different things. Every person to reach this place - I believe upwards of 75mg will always create this experience - will tell you that they feel like one with everything.

DMT is in all humans, all animals and in some plants. Everything alive actually contains the necessary ingredients to synthesize this molecule.

It's also found that we produce large quantities of DMT when we are born, while we sleep and also when we experience death or near-death.

I am a very rational person and like to look at things objectively and I hope the majority of you do too. Can we discuss what this molecule is and it's significance in human history - the use of this through ayahuasca has been done for thousands of years.

Why is this -the- most illegal drug in the world?

DMT is also produced within the pineal gland, a gland that a lot of products like soda, water and foods directly calcify.

I understand that this is a touchy subject because DMT is known as a drug and people like to immediately dismiss ideas that revolve connecting science with illegal drugs. But please try to see this a new thing that hasn't properly been tested.

Wooooooah you mean the same chemical has the same effect on human beings? Woooooooooooooooooooooooooooah

Here's another question, why are almost all psychedelic users such fucking morons?

>It's also found that we produce large quantities of DMT when we are born, while we sleep and also when we experience death or near-death.
False.

>Why is this -the- most illegal drug in the world?
Nonsense.

>DMT is also produced within the pineal gland, a gland that a lot of products like soda, water and foods directly calcify.
False.

>I am a very rational person and like to look at things objectively and I hope the majority of you do too.
Yet you couldn't be bothered to look up evidence for your claims...

>Wooooooah you mean the same chemical has the same effect on human beings? Woooooooooooooooooooooooooooah

This argument will never be plausible. Having the same effects make sense, but to force you into the same experience like I described others having... How can you justify that at all?

I haven't even experienced DMT before but it's undeniably one of the most interesting molecules that hasn't had any -real- research.

I believe it was only hypothesized that we produce it when we sleep etc... To that I will admit the post is a little phony.

Why would people experience something that can better their lives from this? People are often shown everything about themselves and from that, they improve who they were.

Also yeah, it's very illegal. It'll be at the top of any classification in any developed country, yet is has been SHOWN to have many benefits.

>This argument will never be plausible. Having the same effects make sense, but to force you into the same experience like I described others having... How can you justify that at all?
They don't have the same experience, the hallucinations are not even close to be as similar as you describe. If you actually look at the research that's been done, you'll see there is a large variety of hallucinations, and they definitely don't follow some plotline like you think. The fact that many "tropes" of some hallucinations are similar is not surprising, since we expect psychedelics to produce similar hallucinations. What you are asking to be explained, on the other hand, is just something you made up, or heard of and gullibly believed, just like the pineal gland crap.

>I believe it was only hypothesized that we produce it when we sleep etc... To that I will admit the post is a little phony.
No, it was conjectured to be produced while we sleep by one guy, and then a bunch of acidheads turned this into a meme, and you gullibly swallowed it, because you want to believe it. Most rational, objective people would at least attempt to determine the veracity of claims they read on the internet before talking about them.

>Why would people experience something that can better their lives from this? People are often shown everything about themselves and from that, they improve who they were.
This is a self-fulfilling prophecy. People who believe such hallucinations are significant will claim they are significant and revealed deep truths and changed their lives. In reality, they are still losers who can't tell the difference between reality and elves. It's just your subconscious telling you what you want to hear. Part of the hallucination is the illusion that the hallucination is profound.

>Also yeah, it's very illegal.
No bruh it's THE MOST ILLEGAL drug bruh. Bruh. Bruh. Bruh.

Whenever I go to microwave a burrito, I make sure to stand away from the front of the microwave. I'm afraid that some of the microwaves will seep through and energizing my balls. Can someone explain the science behind the safety measures in place with a microwave? How can it be that the sheet with the little holes in them are blocking microwaves 100%?

>energizing my balls

Given that shitposting is a sign of low testosterone you would probably benefit from energizing your balls.

Maybe just put your balls directly in the microwave.
>>
You'd be better served by shielding your balls from eating the plastic-lined burrito container, which you just heated up and caused to leach even more endocrine-disrupting chemicals into your food.
>>
>>8325628
Some microwaves have a degree of leakage. Put a wifi router that works at 2.4GHz near it and see if you find interference if you want a rough test without having to get a specialized sensor.

And no, microwave exposure isn't good for humans, independent of thermals. You should be just as wary of putting your laptop on your lap, or leaving your cell phone in your pocket. Your balls are getting irradiated in much the same way as microwave leakage, just minus the obvious heating.

How do I get hired at a tech company with a math degree?

Most tech companies require one of the below skills:

Programming Experience:
>I have elementary programming experience, but not enough to become a software developer.[taking a class post-graduation but just started].

Data Visualization Experience:
>I don't know Tableau or any other Data Visualization but can learn quickly.

Statistics for analyzing data:
>I only took a basic Statistics course.

SQL:
>Never took a data base course

Certifications:
0 tech certifications

Basically it disqualifies me from most data science, programming and analyst jobs.

I have to look for jobs in marketing, HR, tech support or positions that require a background in something.

Only jobs I'm qualified for are jobs that require no tech skills, no cert skills and 0 background. Might as well not have a degree.

Group theory, Real Analysis, Geometry skillsets are 99.9% useless to majority of companies I'm looking at.

Jobs that are qualified for are ones I don't need a degree for.

NOT trolling. ANY Advice? I'm already going back to school to get skills in those areas I lack. But in the meantime still have a useless pure math degree.

I don't know, man. My interests change so often and so drastically that I can't trust myself anymore. I feel that if I invest any amount of time in such-and-such an interest, it will be a waste because I will just lose that interest and find another one, so I end up just not doing anything but shitpost on 4chan or other superficial activities.

This shit is debilitating. I feel like I am floating along through life, not really making any major progress with anything. I am at the whims of my emotions. I might decide to work through a textbook one day, but I can never make a real commitment because I am concerned about wasting time, though paradoxically I am wasting time anyway being concerned about that.

Is there actually any substantial difference between the following vectors:
(1,1), (1,1,0), (1,1,0,0), (1,1,0,0,0), ...

And why should vector addition or the dot product not be defined for vectors with different lengths? You can just append zeros for the missing coordinates and it would still make sense, provided the first few matching coordinates denote the same property.

Right?

Suppose the following vectors: (1,2) and (3,4,5,6). Normally you'd say: "You can't add them, because vector addition is only defined for vectors of the same length!". Well, you can always take the shorter vector and fill in zeros to get one that matches the length of the other, and then perform addition. And it doesn't really break any logic.

So (1,2) + (3,4,5,6) becomes (1,2,0,0) + (3,4,5,6) which is defined. This applies only when the first few matching coordinates denote the same property, for example "shift in direction of x-axis or y-axis" for the first two elements respectively.

Is there actually a sound reason why this should be forbidden?

That's like giving a knife to a chicken.
>>
>>8324936
Can you explain what you mean without resorting to pretentious metaphors? Thanks
>>
>>8324926

Yes. Because (1,2) is not the same as (1,2,0,0) and you can't add upp vectors that are parts of different R. This all makes more sense once you get into linear algebra and look what actually dimensions and spaces are.

So some people think that star-trek style teleporters entail the destruction of their 'subjective' 'self' or consciousness. Is this just a failing of their object permanence faculties?
